Then, the antenna case316 is fixed to the upper surface side of the shield plate 310 by ascrew 317 so that the printed boards 312 are fitted into the openingportions 311 a to 311 j. In this state, those other than the surfacefaced with the IC tag continuous body 1 are electromagneticallyshielded, and the surface of the printed board 312 on which theloop-shaped antenna element 313 is formed is directly faced with the ICtag continuous body 1 conveyed by the first conveyance unit 62.

In the opening portions 311 a to 311 j and the printed board 312, onlyone corner has a different elongated and substantially rectangular shapeand thus, they are fitted in one unique direction. In the openingportions 311 a to 311 e at the upstream side, the shape of only onecorner at the upstream side is different and thus, in each of the rowantenna units 31 a to 31 e at the upstream side, the antenna terminal314 installed in contact on the end portion of the printed board 312 islocated at the upstream side. Moreover, in the opening portions 311 f to311 j at the downstream side, the shape of only one corner at thedownstream side is different and thus, in each of the row antenna units31 f to 31 j at the downstream side, the antenna terminal 314 installedin contact on the end portion of the printed board 312 is located at thedownstream side. As described above, each of the antenna terminals 314of the row antenna units 31 a to 31 e arranged at the upstream side andeach of the antenna terminals 314 of the row antenna units 31 f to 31 jarranged at the downstream side are respectively arranged in directionsseparated away from each other.

When the IC tags 10 on the second line reach the row antenna units 31 ato 31 e located at the upstream side in the first antenna unit 31, thefact is notified by the conveyance control unit 101 to the writingcontrol unit 102. The writing control unit 102 causes the tag IDs to beread by the tag ID reading unit 121 from the IC tags 10 on theodd-number rows on the second line, respectively (Step A11) anddescribes the read tag IDs in the page information generated at Step A02(Step A12).

When the IC tags 10 on the second line reach the row antenna units 31 fto 31 j located at the downstream side in the first antenna unit 31, thefact is notified by the conveyance control unit 101 to the writingcontrol unit 102. The writing control unit 102 causes the tag IDs to beread by the tag ID reading unit 121 from the IC tags 10 on theeven-number rows on the second line, respectively (Step A14) anddescribes the read tag IDs in the page information generated at Step A02(Step A15). At this point of time, the normal IC tags 10 on the secondline are determined on the basis of the fact whether the tag ID isdescribed or not. The writing control unit 102 sequentially reads theidentification data and the print data to be stored in the normal ICtags 10 on the second line from the product information and describesthe read identification data and print data in the data record of thepage information in which the tag IDs are described (Step A16). FIG. 15Aillustrates a state in which the tag IDs could not be read out of the ICtags 10 on the first row on the second line and the data record on thefirst row on the second line is blank.

The reading of the tag IDs at Steps A04, A07, A11, and A14 may beperformed several times until the IC tag 10 goes out of thecommunication region of the row antenna units 31 a to 31 j (until theloop-shaped antenna elements 14 a of the IC tags 10 go out of theloop-shaped antenna elements 313 of the row antenna units 31 a to 31 j).

The tag-ID reading operation at Steps A1 to A16 is performed in order todetermine whether or not the IC tag 10 functions normally. Therefore,whether or not the IC tag 10 is normal is determined on the basis ofwhether or not the tag ID is described in the page information.

In this case, thecommunication is conducted at the same time in the row antenna units 31a to 31 e located at the upstream side and the row antenna units 31 f to31 j located at the downstream side, but since the row antenna units 31a to 31 j adjacent in the diagonal direction conduct communication byusing different channels, interference can be prevented andcommunication can be reliably conducted with the targeted IC tags 10.

By referring to FIG. 18, the conveyance control unit 101 grasps theconveyance distance of the IC tag continuous body 1 by the detectionresult of the first rotary encoder unit 91 and waits for the arrival ofthe IC tags 10 on the first line at the row antenna units 32 a to 32 elocated at the upstream side in the second antenna unit 32 (Step B01).Specifically, when all the loop-shaped antenna elements 14 a of the ICtags 10 on the odd-number rows on the first line enter the loop-shapedantenna elements 313 of the row antenna units 32 a to 32 e, it isdetermined to be arrival.

When the IC tags 10 on the first line reach the row antenna units 32 ato 32 e located at the upstream side in the second antenna unit 32, thefact is notified by the conveyance control unit 101 to the writingcontrol unit 102. The writing control unit 102 causes the identificationdata described in the page information to be written by the firstidentification data writing unit 122 to the IC tags 10 on the odd-numberrows on the first line (Step B02) and determines whether or not thewriting has succeeded in all (Step B03).

Specifically,when all the loop-shaped antenna elements 14 a of the IC tags 10 on theeven-number rows on the first line enter the loop-shaped antennaelements 313 of the row antenna units 32 f to 32 j, it is determined tobe arrival.

When the IC tags 10 on the first line reach the row antenna units 32 fto 32 j located at the downstream side in the second antenna unit 32,the fact is notified by the conveyance control unit 101 to the writingcontrol unit 102. The writing control unit 102 causes the identificationdata described in the page information to be written by the firstidentification data writing unit 122 to the IC tags 10 on theeven-number rows on the first line (Step B06) and determines whether ornot the writing has succeeded in all (Step B07). Then, if writing in theall has not succeeded and there is the IC tag 10 which failed in writingof the identification data at Step B07, the writing control unit 102extracts the data record including the identification data which failedto be written (tag ID and identification data) from the page information(Step B08) and temporarily stores it in the RAM or the like.

Subsequently, the conveyance control unit 101 grasps the conveyancedistance of the IC tag continuous body 1 by the detection result of thefirst rotary encoder unit 91 and waits for the arrival of the IC tags 10on the second line at the row antenna units 32 a to 32 e located at theupstream side in the second antenna unit 32 (Step B09). Specifically,when all the loop-shaped antenna elements 14 a of the IC tags 10 on theodd-number rows on the second line enter the loop-shaped antennaelements 313 of the row antenna units 32 a to 32 e, it is determined tobe arrival.

When the IC tags 10 on the second line reach the row antenna units 32 ato 32 e located at the upstream side in the second antenna unit 32, thefact is notified by the conveyance control unit 101 to the writingcontrol unit 102. The writing control unit 102 causes the identificationdata described in the page information to be written by the firstidentification data writing unit 122 to the IC tags 10 on the odd-numberrows on the second line (Step B10) and determines whether or not thewriting has succeeded in all (Step B11). Then, if writing in the all hasnot succeeded and there is the IC tag 10 which failed in writing of theidentification data at Step B11, the writing control unit 102 extractsthe data record including the identification data which failed to bewritten (tag ID and identification data) from the page information (StepB12) and temporarily stores it in the RAM or the like.

Subsequently, the conveyance control unit 101 grasps the conveyancedistance of the IC tag continuous body 1 by the detection result of thefirst rotary encoder unit 91 and waits for the arrival of the IC tags 10on the second line at the row antenna units 32 f to 32 j located at thedownstream side in the second antenna unit 32 (Step B13). Specifically,when all the loop-shaped antenna elements 14 a of the IC tags 10 on theeven-number rows on the second line enter the loop-shaped antennaelements 313 of the row antenna units 32 f to 32 j, it is determined tobe arrival.

When the IC tags 10 on the second line reach the row antenna units 32 fto 32 j located at the downstream side in the second antenna unit 32,the fact is notified by the conveyance control unit 101 to the writingcontrol unit 102. The writing control unit 102 causes the identificationdata described in the page information to be written by the firstidentification data writing unit 122 to the IC tags 10 on theeven-number rows on the second line (Step B14) and determines whether ornot the writing has succeeded in all (Step B015). Then, if writing inthe all has not succeeded and there is the IC tag 10 which failed inwriting of the identification data at Step B15, the writing control unit102 extracts the data record including the identification data whichfailed to be written (tag ID and identification data) from the pageinformation (Step B12) and temporarily stores it in the RAM or the like.

The writing of the identification data at Steps B02, B06, B10, and B13may be performed several times until the IC tag 10 goes out of thecommunication region of the row antenna units 32 a to 32 j (until theloop-shaped antenna elements 14 a of the IC tags 10 go out of theloop-shaped antenna elements 313 of the row antenna units 32 a to 32 j).

The writing of the identification data at Steps B02, B06, B10, and B14is performed to the IC tags 10 from which the tag IDs can be read andwhose identification data is described in the page information.Moreover, the writing of the identification data at Steps B02, B06, B10,and B14 is performed directly without checking the tag IDs of the ICtags 10 since the target IC tag 10 is specified. Furthermore, the timingwhen the IC tags 10 on the first line reach the row antenna units 32 fto 32 j located at the downstream side in the second antenna unit 32 atStep B05 and the timing when the IC tags 10 on the second line reach therow antenna units 32 a to 32 e located at the upstream side in thesecond antenna unit 32 at Step B09 can be switched or substantially thesame depending on a pitch of the IC tags 10 or a size or a layout of therow antenna units 32 a to 32 j. In this case, the communication isconducted at the same time in the row antenna units 32 a to 32 e locatedat the upstream side and the row antenna units 32 f to 32 j located atthe downstream side, but since the row antenna units 32 a to 32 jadjacent in the diagonal direction conduct communication by usingdifferent channels, interference can be prevented and communication canbe reliably conducted with the targeted IC tags 10.

Subsequently, the conveyance control unit 101 grasps the conveyancedistance of the IC tag continuous body 1 by the detection result of thefirst rotary encoder unit 91 and waits for the arrival of the IC tags 10in which the identification data is written at Steps B02, B06, B10, andB13 at the communication region of the third antenna unit 32 (Step B17).Then, when the IC tags 10 in which the identification data is written atSteps B02, B06, B10, and B13 reach the communication region of the thirdantenna unit 33, the fact is notified from the conveyance control unit101 to the writing control unit 102. The writing control unit 102 causesthe identification data to be written by the second identification datawriting unit 123 to the IC tags 10 which failed writing of theidentification data at Steps B02, B06, B10, and B13 (Step B18). Thesecond identification data writing unit 123 writes the identificationdata to the IC tag 10 by specifying the tag ID on the basis of the datarecord extracted at Steps B04, B08, B12, and B16.

Since the second identification data writing unit 123 conductscommunication with the IC tag 10 in the electric wave method by usingthe third antenna unit 33, its communication region is wider than thatof the electromagnetic induction method, but since the first antennaunit 31 and the second antenna unit 32 are electromagnetically shieldedexcept the surface faced with the IC tag continuous body 1, interferencewith the communication by the tag ID reading unit 121 or the firstidentification data writing unit 122 is prevented.

Subsequently, the conveyance control unit 101 grasps the conveyancedistance of the IC tag continuous body 1 by the detection result of thefirst rotary encoder unit 91 and notifies the printing device 4 of thearrival of the page. Then, the printing device 4 detects a head of thepage by detecting the detection mark 12 by the fourth sensor 84, printsa page number on the page, and prints the print data described in thepage information on the surface of the IC tag 10 of the page,respectively (Step B19).

Subsequently, when the detection mark 12 of the page is detected by thefifth sensor 85 of the post-processing device 5, the conveyance controlunit 101 notifies the detection of the detection mark 12 to thepage-number reading unit 93 and the writing control unit 102 and causesthe page-number reading unit 93 to read the page number printed on thepage (Step B20). The reading of the page number is performed in order tospecify the page. Therefore, a sign such as a barcode may be printedother than the page number so as to be read, but by printing the pagenumber with which the user can directly recognize the page, manualinspection can be facilitated.

Subsequently, the writing control unit 102 causes the identificationdata reading unit 124 to read the tag ID and the identification datafrom the IC tag 10 of the IC tag continuous body 1 being conveyed by thefourth conveyance unit 67 by using the fourth antenna unit 51 (StepB21). Then, the writing control unit 102 compares the tag ID and theidentification data read at Step B21 with the page information of thepage number read by the page-number reading unit 93 (Step B22) anddetermines whether or not all the data records are matched (Step B23).

If there is an unmatched data record at Step B23, that is, if theidentification data described in the page information could not be reador if the identification data is written to the IC tag 10 with the tagID different from the page information, the identification data and theprint data as the unmatched data record are described as reissuanceinformation in the reissuance information storage portion 113 (StepB24). FIG. 15B illustrates an example in which the identification datadescribed in the page information could not be read from the IC tag 10on the fifth row on the first line and the identification data and theprint data of the fifth row on the first line are described as thereissuance information.

Subsequently, as illustrated in FIG. 14B, by using the identificationdata as a key, the tag ID of the data record determined to be matched atStep B23 is described in the product information (Step B25), and theissuing operation for one page is finished. The issuing operation atStep A01 to Step B25 is subjected to parallel processing for each page.Then, after the issuing operation on the basis of the productinformation is finished, the issuing operation on the basis of thereissuance information is performed.

The writing control unit 102 notifies position information of the IC tag10 from which the tag ID could not be read and the IC tag 10 whoseidentification data did not match the page information to the embossprocessing unit 52. Then, the emboss processing unit 52 applies theemboss processing to and issues the IC tag 10 from which the tag IDcould not be read and the IC tag 10 whose identification data did notmatch the page information.

As a result, when the issued IC tag continuous body 1 is cut andaligned, the IC tag 10 in which the identification data could not becorrectly written can be selected easily and can be replaced by the ICtag 10 issued on the basis of the reissuance information.

In this embodiment, 10 rows*2 lines of the IC tags 10 constitute onepage, but the number of rows and the number of lines constituting onepage are arbitrary. In accordance with the number of rows and the sizeof the IC tags 10 constituting one page, the numbers and layout of therow antenna units 31 a to 31 j in the first antenna unit 31 and the rowantenna units 32 a to 32 j in the second antenna unit 32 are set asappropriate.

As described above, according to this embodiment, the IC tag issuingapparatus for writing the identification data to the IC tags 10 arrangedin multiple rows aligned as the IC tag continuous body 1, respectively,and issuing the result includes the second antenna units 32 arranged toface each row of the IC tags 10 in multiple rows, respectively, andfunctioning as a plurality of writing row antenna units for writing theidentification data to the IC tags 10 by the electromagnetic inductionmethod and a third antenna unit 33 arranged at the downstream side inthe conveyance direction of the IC tag continuous body 1 from the secondantenna unit 32 and functioning as the electric-wave type antenna unitfor writing the identification data to the IC tags 10 by the electricwave method and is constituted to write the identification data by usingthe third antenna units 33 to the IC tag 10 in which the identificationdata could not be written by using the second antenna unit 32.

By means of this constitution, even if the IC tag 10 in which theidentification data cannot be written by increasing the conveyance speedof the IC tag continuous body 1 and by using the second antenna unit 32is generated, the identification data can be written by the thirdantenna unit 33 and thus, the communication processing with the IC tagcan be conducted at a high speed and reliably, whereby the issuancespeed can be improved.

Moreover, according to this embodiment, on the upstream side of the ICtag continuous body 1 in the conveyance direction from the secondantenna unit 32, the first antenna unit 31 arranged to face each row ofthe IC tags 10 arranged in multiple rows, respectively, and functioningas a plurality of reading row antenna units for reading the unique tagID from the IC tag 10 by the electromagnetic induction method isprovided and it is constituted so that the identification data iswritten by using the second antenna unit 32 to the IC tag 10 from whichthe tag ID could be read by using the first antenna unit 31.

By means of this constitution, since it can be excluded from the writingtargets of the identification data of the IC tag 10 from which the tagID cannot be read, the writing efficiency of the identification data canbe improved, and the issuance speed can be increased. Moreover, sincethe second antenna unit 32 only needs to directly write theidentification data without reading the tag ID from the IC tag 10, timefor writing the identification data can be reduced.

Moreover, according to this embodiment, the writing of theidentification data using the third antenna unit 33 is performed byspecifying the tag ID.

By means of this constitution, in writing of the identification datausing the third antenna unit 33, the IC tag 10 in which theidentification data could not be written by using the second antennaunit 32 can be specified in a pinpoint manner.

Moreover, according to this embodiment, in the second antenna unit 32,the surfaces other than the surface faced with the IC tag 10 of the ICtag continuous body 1 is electromagnetically shielded.

By means of this constitution, interference between the communicationusing the second antenna unit 32 and the communication using the thirdantenna unit 33 can be prevented.

Moreover, according to this embodiment, the first conveyance unit 62 andthe second conveyance unit 63 are provided as the conveyance unit forconveying the IC tag continuous body 1 while suctioning it to theconveyance belts (62 c, 63 c), and the second antenna unit 32 isarranged to face the IC tags 10 of the IC tag continuous body 1 conveyedby the first conveyance unit 62, and the third antenna unit 33 isarranged to face the IC tags 10 of the IC tag continuous body 1 conveyedby the second conveyance unit 63.

By means of this constitution, the IC tags 10 of the IC tag continuousbody 1 can conduct communication in a state reliably faced with thesecond antenna unit 32 and the third antenna unit 33, wherebycommunication accuracy can be improved.

The present invention has been described by using the specificembodiment but the aforementioned embodiment is an example, and it isneedless to say that it can be changed and put into practice within arange not departing from the gist of the present invention.
